Fully Transparent Production

Complement Plus goes through a rigorous inspection process, that includes third party testing.

We want you to be certain that you are getting the highest quality nutrients, free from pollutants, heavy metals, and harmful pathogens — not to mention common allergens and artificial sweeteners, colors and flavors. That’s why every batch undergoes a rigorous series of tests to confirm that it contains all that it should - and nothing that it shouldn’t.

And we mean rigorous! Everything from hand inspection of each capsule to as many as 19 different test to ensure potency and safety. All this done in pharmaceutical-grade facilities that are FDA Registered, and operate under cGMP standards.

THIRD PARTY TESTING. This means that every ingredient and dosage on the back of the bottle is verified by an independent lab. And just as important, the ingredients are tested for things like pesticides, E Coli, heavy metals, and salmonella.

  • potency

    We verify that all active ingredients on the label are present in the right amounts. But we're not satisfied with just meeting those - to ensure potency over time does not diminish, we aim for 10-20% over what the label states.

  • Heavy Metals

    We take soil and water pollution seriously, especially since we design our products to help your body fight against it. Therefore, each batch gets tested for Arsenic, Cadmium, Lead and Mercury.

  • Pathogens

    Our products are doubly protected by being produced in a certified facility, and tested for yeast and mold, and possible bacterial presence, such as Salmonella, E.coli and other coliforms.

The Complement Plus Formula

Premium Plant-Based Nutrition
  • The 'Big 3'

    Complement Plus is based on the same basic formula as Complement spray, providing B12, D3 and long-chain Omega-3s - the essential nutrients that even well-designed vegan diets often lack.

  • The Essential Extras

    Based on the prevailing science, we included the essential nutrients that aren't found abundantly in, or aren't adequately absorbed from, plant foods: iodine, Vitamin K2, magnesium, selenium and zinc.

  • The Smart Parts

    The Plus sign isn't just for the extra nutrients - it's for what they do together. We've made sure that the ingredients truly complement each other, improving the absorption rates and their beneficial effects in the body.

All Natural Ingredients

The Plus isn't just about extra nutrients - it's about what they do together. We've made sure that the ingredients truly complement each other, improving the absorption rates and their beneficial effects in the body.

Our Omegas are better absorbed than fish oil.

Complement Plus is made with Almega®PL, the only algal oil where the Omega-3s are bound with polar-lipids (phospholipids and glycolipids) – providing the health benefits of EPA with enhanced absorption. Almega®PL naturally contains other beneficial compounds including carotenoids, Omega-7, and Chlorophyll.

The Smart Part: Studies show that the polar lipids present in Almega®PL algal oil make the absorption rate of DHA and EPA up to 50% higher than krill oil, and 130% higher than fish oil. Complement Plus™ includes 90 mg of polar lipids per daily serving, sourced from algae grown under controlled conditions and tested for purity.


The Black Capsule

We believe in only using necessary ingredients and artificial colors are not among them!

Rather than being processed and refined, the oil used in Complement Plus naturally contains other beneficial compounds including carotenoids, Omega-7, and Chlorophyll - which gives it a dark green color that appear nearly black.

Frequently Asked Questions

Who is Complement?

We’re an all-vegan team on a mission to support the health of the vegan movement, by protecting the health of individual vegans with the nutrients they need to thrive. Through sourcing the highest quality ingredients and fully transparent production, we leave absolutely nothing on the table when it comes to developing essential, premium plant-based nutrition products.

is complement plus vegan?

Yes, Complement Plus™ is vegan and cruelty-free. (And so are we.) All of the ingredients are sourced from plants, bacteria, minerals or algae.

why did you make the capsules black?

What you see when you look at Complement Plus™ capsules is the natural color of the Almega®PL algal oil we use. Rather than being a processed, refined oil, Almega®PL naturally contains other beneficial compounds including carotenoids, Omega-7, and Chlorophyll - which gives it a dark green color that appear nearly black in the capsules. We believe in only using necessary ingredients - and artificial colors are not among them!

what does complement plus taste like?

Being a capsule, Complement Plus™ should be swallowed without holding it in the mouth, so there's no specific flavor to expect.

should i take all 3 capsules at once for the daily dose, or one with each meal?

There shouldn't be any difference between taking all three capsules with a single meal, or spacing them throughout the day.
The one thing that is somewhat important is taking them with meals that contain at least some amount of fat, as this will help with the absorption of the nutrients.

can my children take complement plus?

We formulated Complement Plus™ for adults and kids over 12. If you wish to give it to younger children, please consult with your doctor or pediatrician and show them the full ingredients list to determine its suitability and dose. Also, please keep in mind that while most adults and older children have no issues swallowing the capsules, they might be a bit big for younger children. Have a look at Complement spray ( for an alternative that most of our team members use for their toddlers.

can i take complement plus together with my multivitamin or other supplements?

Complement Plus™, together with a whole-food, plant-based diet, will provide you with the nutrients you need to thrive. Formulated for optimal nutrient intake, Complement Plus™ is safe and non-toxic when taken as directed. If you take another supplement that contains any of the nutrients found in Complement Plus™, you may exceed the tolerable upper intake for that nutrient. Speak with your doctor if you have any questions about how Complement Plus™ works with any other supplements or medications you are taking.

when can i expect my order?

Complement Plus™ is in stock, and you can expect your order in 5-7 business days after placing it (international delivery times will vary, of course).
